High Quality Content by WIKIPEDIA articles! The XY no trump convention is a convention in bridge. After opener's one of a suit (X), partner's one of a suit response (Y) and opener's 1NT rebid (a very common sequence), 2? from opener's partner forces 2? from opener. Holding a weak hand with diamonds, one can now pass. Other bids are invitational, describing also the nature of the hand. A 2? response to 1NT, however, is game forcing with any hand.For example, on the sequence 1?-1? (with our without opponent's interfering); 1NT-2?;2?,2? will show an invitational hand with minimum five spades and four hearts, 2? an invitational hand with minimum five spades (in which case one does not have four hearts) or possibly six spades with or without four hearts. 2NT will show a balanced invitational hand, 3? typically an unbalanced invitational hand with club support.
